IC tag unit for instrument, and instrument with IC tag

Abstract

An IC tag unit, for an instrument, which allows an IC tag into and from which instrument information, calibration information, inspection information, and the like can be written and read to be mounted to an instrument without affecting the IC tag by a metal portion of an instrument body, hindering visibility of a scale of the instrument, and further causing degradation due to dust, raindrops, or the like, and an instrument with the IC tag, are provided. An IC tag 11 having an IC chip 12 and an antenna 13 , and mounting means configured to mount the IC tag to an instrument, are provided, and the instrument has scale increments and a pointer, and a transparent cover plate 53 that covers the scale increments 56 a and the pointer. The mounting means includes: a first sheet disposed on an outer side surface of the instrument; a second sheet that is disposed on an inner side surface of the instrument and that sandwiches the IC tag; and an attachment layer that allows both the sheets attached to each other to be attached to the transparent cover plate. The IC tag is disposed between both the sheets so as not to overlap the scale increments 56 a and an indicator portion 55 a of the pointer 55 in a viewing direction, and a developed plane of the antenna is arranged along both the sheets, when the IC tag is mounted to the transparent cover plate.
